Introduction One of the main features of modern high technologies is the desire to create and use new materials that have, in addition to a unique combination of mechanical, physical, and other properties, the ability to actively respond to changes in external conditions or external influence (smart materials).
In this regard, the formation of nanostructured states in materials with shape memory effect (SME), both in the bulk and on the surface, is an important aspect of modern materials [1–5].

Since each kind of materials has a certain characteristic absorption, in other words, it only absorbs certain wave length instead of others, this character can be used to analyse the material qualitatively.
Apart from this, the sum of the materials is proportional to the total absorption.

Materials and Methods Over the past 3 years, supported by the National Natural Science Foundation of China (No. 41103026), the large scale geological mapping, geological-section, tectonic and geochemical studies on the carbonate-hosted Pb-Zn deposits in NE Yunnan had been carried out, which were focused on the most representative large-sized deposits, such as the Huize and Maoping Pb-Zn deposits (Fig. 1).
The collected data and detailed field studies on the Huize and Maoping deposits indicate that the concentration and mineralization of lead and zinc in NE Yunnan need several geological conditions. (1) strata and lithological conditions: most of the Pb-Zn deposits are hosted in Paleozoic carbonate rocks, especially in the medium-coarse crystalline dolomite, the carbonate rocks are requisite to Pb-Zn mineralization, and they provide some ore-forming materials [5]; (2) tectonic conditions: the Pb-Zn deposits are controlled by the regional faults, and the ore-bodies are mainly distributed in the interlayer fracture zones of carbonate rocks, which formed by regional thrust fault-fold structures, indicate that the regional tectonic activity is crucial to the migration and deposition of ore-forming materials, the induced fold or compresso- shear structural plane is major ore-contained space; (3) magmatic constraints: the Upper Permian Emeishan basalts are widely distributed at the outer surrounds
